LLINOS, A CORPORATON OF ILLINOIS CAR DOOR Application le. April 24,

said upper and lower supports there is a l tendency for the door to sag and buckle vertically and also .to warp on diagonal lines. Various expedient-shave been suggested to overcome such defects7 such as forming the vertical margins of stronger and heavier sections and placing additional horizontal cross members from one verticalfmargin to the other lbut such construction calls for greatly added weight which renders the door excessively heavy and expensive.

It is an object of myvinvention to provide` a construction for a freight car door which will strengthen the same against warping and buckling and still be light in weight and relatively cheap. Q. i

lt is also a further object of my invention to provide a door construction which will permit of reinforcement byy rigidifying embossments defining intelligible indicatory symbols, whereby the ydoor will not only possess strength but also have advertisingl a ue.

A still further object of my invention is to provide a freight ca'r door having the body formed mainly of metal sections of different thicknesses and to provide additional reinforcing members having considerable body whereby the strength of the thicker sections of the door will operate to brace and strengthen the sheets formed of thinner material.

Other objects of the invention will more clearly appear from the description hereinafter following. Y

ln the drawings` forming a part of this specification, Fig. 1 is a front elevational viewl of a freight car door'e'mbodying my improvedoor opening7 the 1926. Serial No. 104,426.

ments.V Fig. 2 is a vertical sectional view taken through the door and on a line-corresponding substantially to a line 2-2 of `Fig. 1. Fig. 3 is an enlarged horizontal sectional view corresponding substantially to a line 3-3 of Fig. 1, intermediate parts being broken away to better accommodate the view on the sheet. In this figure various details of the car construction adjacentthe door are illustrated. Fig. 4 is a sectional view illustrating the lower portion of the door in relation to the supporting structure when such support is disposed `at the bottom of the door instead of at the top thereof.

ln said drawings, the usual front and rear door posts defining the door opening of a bor; car are illustrated at and 11 respectively, and the threshold of the door opening is indicated at 12. The improved door is indicated generally by the reference character d As shown, the door includes a marginal rectangular frame which includes atop horizontal member 13, and front and rear vertical marginal members as indicated at 14 and 15 respectively. The said marginal members A13. 14 and 15 are preferably formed of Z- shaped rolled sections with flanges 16, 1T and 18 of the respective marginal members disposed in the-.front plane of the door and the intermediate webs of the respective members project inwardly of the front plane of the door and are disposed substantially at rightangles thereto. The respective vertical marginal members le' and 15 are braced to :the top member 13 by gussets 19-19. rlhebody of the door intermediate the said frame members is preferably formed of two sheet metal panels as indicated at and 21. rlihese panels are preferably overlappingly united to each other along a horizontal line of rivets as indicated at 22, said jointk being disposed at an appreciable distance above the lower margin of the door. i The edges ofthe respective panels 20-21 are secured flatwise to the inwardly projecting flanges 16,17 and 18 of therespective marginal members 13, 11i and 15. i

The lower margin of the Vdoor is rigidified panel 21 inwardly as indicated at 23 and Y thence downwardly, thereby presenting a depending flange 24 disposed at an appreciable distance from the front plane of the door. The lower panel 21, which is preferably made of thicker material than the upper panel 20, thus serves v"as, a strong member )for the Ylower portion of the door, Iand serves to maintain the frame against racking and also kprotects thelowerpart of the door against injury, due yto'shifting'loads in the car. "Secured 'tosaid dependingiflange 24 o'f'the lower panel 21 on the inner side of the door is a hat plate 25 which extends upwardly above the lower-'margin of the door for anappreeia'ble distance, and provides a smooth and even surface for centac'ting with the `rcar structure l2 "at "the lower Aportionofthe door 'opening the door 'is mo'ved. Interposed'tbetween 'said 1' plate 25 and the paneling of 'fthe door Iis a wooden lbeiam member 26 which 'also acts f' as a :"iiller "member, and?operatesftostrengthen the door against bending 'and warping. This-'arrangement 11n' conjunction with 'the strong V"lower 'fp'anel'21 provides'ankexceedingly strong con- Ast'r-i'lc't-i'on at the lower margin of the door. Extending upwardly-*and outwardly from v the central portion of vthe 'beam*member 26 l"are braces `427427', Iwhich together form "a V- shaped reinforcement extending 'upwardly for rfprefe'rably more than fhalf "the "vertical 'height 'ofthe door. The said braces 27--27 extended outwardlyto-meetlth'e'fvertical y lmarginal reinforcements-cooperate with the same l'to r'esisftbending of the door on vvertical lines. graces 27-27 Eare preferably 'formed loff Wooden Vbeams V"uni-ted by soft 'rivets v'268 -to `tiVelythnner panel '20,a-ndjin thisimann'er a :portion of the strength Ioff the lower Vheavy V`form df intelligible* inc'lieatoiy `characters or `symbols 4 The emboss'ment lis lpreferably fforrnedjo'i: a size to rigidity fthe Iunshpported portion offithe plate" and'- inthe present ldesign "embodied in `vthis "invention it will-be seen l"that Vthe diamond VVAshape 530' extends between r'therespective'vertifial marginal beams 14' an d "I5 ."whil'e I'the circular portion '3l lextends tanfgent to the 'V 'arranged bracing structurev*formed zbyfbraces 2T-#27.
